Scientists Found Black Hole’s Twin – And It’s Even Scarier - video Dailymotion

Bright Side

Scientists found a black hole’s twin, and somehow, it’s even scarier than the first one. This cosmic monster is massive, lurking in the depths of space, swallowing everything that comes too close. What makes it even creepier? It’s eerily similar to another supermassive black hole we already know—meaning there could be more of these lurking around the universe. Scientists are now racing to figure out how it formed and what it means for our understanding of black holes. One thing’s for sure: space just got a little more terrifying! 🚀  Credit: LLO Control Room: By Amber Stuver, CC BY-SA 4.0 https://creativecommons.org/licenses/by-sa/4.0, https://commons.wikimedia.org/w/index.php?curid=46993713 CC BY 4.0 https://creativecommons.org/licenses/by/4.0: Black hole: By Event Horizon Telescope, https://commons.wikimedia.org/w/index.php?curid=77925953 M87 supermassive black hole: By EHT Collaboration, https://commons.wikimedia.org/w/index.php?curid=102736603 Animation is created by Bright Side.  ---------------------------------------------------------------------------------------- Music from TheSoul Sound: https://thesoul-sound.com/   Check our Bright Side podcast on Spotify and leave a positive review! https://open.spotify.com/show/0hUkPxD34jRLrMrJux4VxV   Subscribe to Bright Side: https://goo.gl/rQTJZz ---------------------------------------------------------------------------------------- Our Social Media: Facebook: https://www.facebook.com/brightside Instagram: https://www.instagram.com/brightside.official TikTok: https://www.tiktok.com/@brightside.official?lang=en Telegram: https://t.me/bright_side_official   Stock materials (photos, footages and other): https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru ----------------------------------------------------------------------------------------  For more videos and articles visit: http://www.brightside.me  ---------------------------------------------------------------------------------------- This video is made for entertainment purposes.

00:00Scientists think there might be a huge onion chilling somewhere out there in space.

00:05Not an actual one, but it's something even crazier.

00:08These are stars stacked inside each other, layer upon layer.

00:13These fascinating objects, called gravastars, could even be cousins of black holes.

00:19But most importantly, they might hold the key to understanding some of the most mysterious puzzles in the universe,

00:26dark energy, and even other dimensions.

00:30Let's start with gravity.

00:32Over a century ago, Albert Einstein helped us understand how gravity works.

00:38Turns out, it's not just something that pulls things on Earth and makes apples fall on Newton's head.

00:45It's much wilder.

00:47It's about warping the very fabric of existence itself.

00:51Let's say you toss a heavy ball, like a bowling ball, onto the middle of your bed.

00:56What happens to the sheets?

00:58They dip, don't they?

01:00They stretch and sag around the ball.

01:03Now, if you roll a smaller ball, like a marble, across the bed, it doesn't move in a straight line anymore.

01:10Instead, it starts circling the heavy ball, rolling closer and closer, as if the heavy ball is pulling it in.

01:17That's gravity!

01:19But instead of bedsheets, we're talking about the fabric of space and time itself, or space-time for short.

01:27Heavy objects like planets and stars make dents in space-time, and moons, planets, or even light move along these dents.

01:36Gravity is the curve that tells them where to go.

01:40In that case, you can guess that black holes are like the ultimate heavy balls.

01:45The heaviest, in fact.

01:47The gravity is so strong, it shrinks them, making them smaller and smaller.

01:52So tiny, they could fit in the palm of your hand, but with the mass of several suns.

01:58Some of them are like holding over 40 billion solar masses in your palm.

02:03It's ridiculous, but they basically create a bottomless pit in space-time with insane gravity.

02:10This area around them, called the event horizon, is the most horrifying thing ever.

02:16It's a point of no return.

02:19Once something gets there, it can never escape being eaten.

02:23When something falls past the event horizon, it can't climb back out, not even light.

02:29Which is why they seem like, well, black holes.

02:33But gravastars, they're something much weirder.

02:36Just like black holes, they're probably very compact.

02:40But instead of being tiny pits of endless gravity, they might have something wild at their core.

02:46Dark energy.

02:48This is one of the universe's biggest mysteries.

02:51Dark energy, this invisible, mysterious something that seems to be pushing the universe apart faster and faster.

02:59It's like a polar opposite of gravity.

03:02While gravity tries to pull things together to slow down the expansion of the universe,

03:07dark energy is trying its hardest to make our world even bigger.

03:12Luckily, dark energy has been winning so far.

03:15Otherwise, we'd all be in some deep pit.

03:18But if we can explain the gravity with balls, then what exactly is dark energy?

03:24A force? An energy field? Something else?

03:28We have no idea.

03:30Scientists have seen its effects.

03:32They know that it's incredibly spread out everywhere.

03:35But they can't tell you what that thing even is.

03:39But if it's trapped inside of gravastars, maybe we'll finally discover the truth.

03:45This name stands for gravitational condensate stars.

03:49Gravastars were dreamed up by two physics professors, Paolo Mazur and Emil Mottola, in 2006.

03:56They tried to think what else, besides black holes, could happen when a massive star collapses on itself.

04:04That's how they created this alternative.

04:07Think of it this way.

04:09Gravity pulls everything inward, making super-heavy objects like stars shrink in size.

04:15The more the star shrinks, the denser it gets, and its gravity grows stronger.

04:20After some point, it can cross a critical threshold and become a black hole.

04:26But what if there was dark energy inside to counteract this?

04:31At the core of a gravastar, there could be a region filled with false vacuum or dark energy.

04:37This energy would push outward, fighting the gravity.

04:41It's like the unstoppable force meets an immovable object.

04:45Thanks to this, the star core doesn't collapse into a black hole.

04:50Sounds wacky.

04:52We don't know what dark energy even is, so how can it fill up anything?

04:57But luckily, even if scientists can't fully explain dark energy,

05:01they still have strong mathematical models to check how it works in our universe.

05:06So, they decided to test this theory.

05:09Here's where things get even weirder.

05:12The new theory says that gravastars might not be simple lone objects.

05:17Instead, they could be stacked one inside another.

05:21Each one is like a layer with its own dark energy bubble inside, surrounded by a thin skin of matter.

05:28The outermost shell would hold a smaller gravastar inside it,

05:32and that one could hold an even smaller one, and so on.

05:36It's like a series of balloons, one inside the other.

05:39The air pressure in each one of them is stable, evenly spread out.

05:43Thanks to that, none of them deflate.

05:46They coexist without one popping or collapsing the others.

05:50In the case of gravastars, the air is dark energy,

05:54and the rubber is the shell of matter surrounding it.

05:57It sounds crazy, but it actually makes this whole idea more realistic.

06:01A single gravastar might have a very thin shell of matter,

06:05but the thicker they are, the more likely it is to exist in a stable way.

06:10And finally, the coolest part about them is that they could explain one of the biggest mysteries of our world,

06:17how universes are born.

06:20When a star collapses into a gravastar,

06:23the matter could theoretically implode through the center and create a new dimension.

06:29This would connect these objects to the Big Bang itself.

06:34Some scientists even speculate that dark energy could be the energy exchanged between our universe

06:40and a child universe that's created from a gravastar.

06:44Of course, these are all just speculations for now.

06:48But where are all those gravastars, and how do we test this?

06:52Well, physicists aren't sure either.

06:55They're more of a what-if thing than an actual object that they discovered.

07:00Those two professors just tried to imagine what would happen if gravity and dark energy worked together like this.

07:07For now, the LIGO, a big observatory which detects ripples in spacetime,

07:12hasn't found clear evidence of gravastars.

07:15Another problem is that gravastars would only be stable in specific cases.

07:20For example, if they spin too fast or their shell will be too thick,

07:24they might start to wobble or break apart eventually.

07:28Though it could actually take billions of years.

07:31Plus, even if we don't see them right now,

07:34remember that this is exactly what happened to the black holes themselves.

07:38When Einstein published his groundbreaking theory of general relativity,

07:43another scientist, Carl Schwarzschild, took his equations and found a solution to them.

07:49And that's when he realized, if gravity becomes incredibly strong,

07:54the light wouldn't be able to escape, and this could create a sort of hole in space.

08:00Einstein even thought that this sounds too weird to be true.

08:05It took many years for us to confirm black hole's existence,

08:09and we finally took a photo of one just a couple of years ago.

08:13You might remember that blurry picture that blew up online?

08:17It was Sagittarius A star, an incredible supermassive black hole in the center of our galaxy, Milky Way.

08:25So, that's why scientists approach gravastars so seriously.

08:30And since all the math checked out, which means that these objects are actually possible in real life.

08:36Now, we just need to see if they're somewhere out there.

08:40What's interesting is that they'd probably look like regular black holes.

08:44They could emit high energy radiation as they consume matter.

08:48They might even produce something called Hawking radiation,

08:52a type of energy that escapes from black holes.

08:55In other words, it would be nearly impossible to tell the difference.

08:59But gravastars have a small trick up their sleeve.

09:02If their shell is transparent to light, they might bend light in a slightly different way than black holes do.

09:09So maybe if they check the way light is bent around the mysterious object, they could spot the difference.

09:16And even if it turns out that gravastars don't exist in our reality, they're still valuable to science.

09:23They still taught us more about gravity, black holes, and the limits of relativity.

09:33That's it for today!
